BOBBIN-SUPPORTING PIN FOR A CREEL.

Specification of Letters Patent.

Patented July 241:, 11ml "1..

Application filed September 12, 1916. Serial No. 119,658.

To all whom it may concern:

Be it known that I, OULLEN L. LYTTON,

a citizen of the United States of America,

and a resident of Withers, county of Gaston, State of North Carolina, have invented certain new and useful Improvements in Bob bin-Supporting Pins for Greels, of which the following is a full and clear specification.

The object of this invention is to greatlyv reduce the friction of the running of the creel bobbin, so as to thereby reduce the danger of the yarn or roving breaking between the creel and the twisting or roving mechanism, this breaking of the yarn being a well known cause of considerable delay in running the machine and waste of yarn, as more fully hereinafter set forth.

In the drawing Figure 1 is a vertical sectional view; and

Fig. 2 a cross section on the line 22 of Fig. 1.

In the drawing, a designates the usual bobbin pin or spindle, which is rigidly supported in an upwardly-inclined position by means of the usual creel frame bar 6. At the base of the pin a is a collar or washer c, in the face of which is mounted an antifriction ball d, against which the end of the bobbin 6 normally bears when mounted on the pin.

On the upper side of the pin a is mounted a series of freely rotatable anti-friction balls 7, set in suitable recesses in the pin. I prefer mounting each ball in a metal cup 9, which is fitted into a transverse recess formed in the pin, this cup being adapted to be removed by use of a simple tool to enable it to be renewed when the cup or the ball becomes worn or broken. The cups will be case hardened to reduce wear to a minimum.

The pull of the yarn or roving is directly downwardly, as usual, and, therefore, by mounting the balls along the upper side of the pin the tendency will be to hold the spools directly against the balls and away from the under side of the pin, thereby reducing friction to a minimum. I prefer mounting two of the balls near each end of the pin, the balls of each pair being arranged on opposite sides of a vertical plane taken through the axial center of the pin.

Having thus described my invention, what I claim is:

In a device of the class set forth, a pin and means for supporting it stationarily, said pin being provided with freely rotatable anti-friction balls along its upper surface, an anti-friction device at the inner end of the pin, and a bobbin fitting on the pin, and having its bore bearing on the balls carried by the pin and its inner end bearing against said anti-friction device.

In testimony whereof I hereunto affix my signature.

OULLEN L. LYTTON.
